Abstract

The invention provides a green fertilization method for a peach orchard, and belongs to the technical field of agricultural planting. The fertilizing method comprises the following steps: (1) after picking, applying a base fertilizer and a microbial agent to roots; (2) applying a compound fertilizer and a water-soluble fertilizer to roots in a germination stage, wherein the water-soluble fertilizer comprises potassium dihydrogen phosphate and medium elements; (3) applying compound fertilizer to roots in a core hardening stage; (4) in a fruit development stage, applying compound fertilizer to roots and spraying foliar fertilizer to leaf surfaces, wherein the foliar fertilizer comprises pyroligneous liquor and trace elements. According to the peach tree fertilizing method, a microbial agent, a water-soluble fertilizer, and a foliar fertilizer are cooperatively applied, so that the synergistic interaction effect is achieved, the content of nitrate and titratable acid in peaches can be remarkably reduced, the content of soluble total sugar and the content of vitamin C can be increased, the yield of the peaches is increased, and the quality and taste of the peaches are improved.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a green fertilization method for peach orchards. Background technique [0002] Peach is originally produced in my country, and it is distributed all over my country, and the planting area is very large. The production value of peach is very high, peach fruit can be used for food, flower can be used for viewing and viewing, peach fruit juice is much delicious, and contains trace element and vitamin needed by human body, has very high nutritional value. During the entire growth period of peach trees, the plants need to absorb a large amount of nutrients from the soil to meet the needs of the plant growth. During the peach tree production process, a large number of topdressing fertilizers are required to meet the nutrient requirements of the plants. However, a large amount of fertilization will lead to a series of adverse problems such as soil quality degr...
